About This Item
ASTM F3348 is the standard specification for plastic press insert fittings with factory assembled stainless steel press sleeves for SDR9 cross-linked polyethylene (PEX) tubing and SDR9 polyethylene of raised temperature (PE-RT) tubing. It provides a focused technical basis for evaluating fittings intended for press-connection systems used with these tubing materials. As a product-page reference, ASTM F3348 helps buyers and specifiers identify a standard designed to support consistent fit, material compatibility, and performance expectations for this type of piping component.
ASTM F3348 standard overview
This ASTM standard addresses a specific fitting construction: plastic press insert fittings with a factory assembled stainless steel press sleeve. Its title indicates application to SDR9 PEX tubing and SDR9 PE-RT tubing, making it relevant to products intended for those pressure piping systems. ASTM F3348 is useful for defining a common specification framework so manufacturers, distributors, and specifiers can align on the fitting type, intended tubing compatibility, and general compliance expectations for engineering and procurement purposes.
Where is ASTM F3348 used?
ASTM F3348 is commonly used in the context of press-fit plumbing and piping products designed for SDR9 PEX and SDR9 PE-RT tubing. It is relevant wherever plastic insert fittings with stainless steel press sleeves are selected for system assembly, product evaluation, or purchasing decisions. The standard helps support clear identification of fittings intended for these tubing materials, which is valuable for contractors, engineers, and supply teams working with compatible press connection components.
Practical importance of ASTM F3348
In practice, ASTM F3348 matters because it helps establish a shared specification for a specialized fitting configuration. That can support more consistent product selection, quality control, and compliance review when evaluating press insert fittings for PEX and PE-RT tubing. It also helps reduce uncertainty in procurement by tying the product to a defined ASTM standard. For manufacturers and specifiers, this can improve comparability, documentation, and confidence in product suitability.
